A majority of Americans believes home-grown jihadists are a greater terror threat than those who are foreign-born, and that overseas terrorists are trying to slip into the country, according to a poll released Wednesday.

The Quinnipiac survey found that 55 percent of voters believe radicalized Americans pose the greatest threat to the United States, while only 18 percent said foreign terrorists should be the biggest fear.

Americans remain torn on allowing Muslims to immigrate to the United States.
